A casino is a gambling establishment where patrons place wagers on games of chance. It was a popular pastime in the European royal courts of the 17th and 18th centuries, and it became more widespread in the latter half of the 19th century as states began changing their laws to permit them. Casinos are usually regulated by government agencies to ensure that their operations are fair and honest. Many casinos have security measures in place to deter crime and cheating by employees or patrons, especially since large amounts of money are handled there. These can include a physical security force and a specialized department for video surveillance, commonly known as the “eye-in-the-sky.”
The exact origin of gambling is unknown, but it has been a popular activity in nearly every society throughout history. Modern casinos are much like an indoor amusement park for adults, and most of their profits come from the billions of dollars that customers spend on games of chance. Slot machines, blackjack, roulette, baccarat and other games provide the thrills that attract customers.
Casinos have a tainted image, and it was not uncommon for mobster funds to flow into casinos in Reno and Las Vegas in the 1950s. Mafia members often took sole or partial ownership of the casinos and even exerted control over gaming decisions. Nowadays, casinos are regulated by state governments, and they employ sophisticated technology to deter crime and monitor their customers. For example, windows are rarely placed in casino floors, and clocks are not visible to patrons, so they cannot know how long they have been playing.
